The Lowdown

Alright, Rusty here. Let’s break down the next couple of weeks at Jaconé. It starts off slow, but there’s a proper stretch of swell coming that’ll get your attention.

Right now, the ocean is pretty flat. Water temp is 72°, which is normal for this time of year. Tuesday afternoon and Wednesday morning have tiny waves – 0.7m to 1.0m from the east, with a short period of 7 seconds, and the combined energy is weak (127). The wind is okay, but the swell is too small. Wednesday morning has a clean window with offshore wind for that 0.7m, but it’s nothing to get excited about.

The first real pulse arrives Friday morning the 21st. Swell jumps to 1.9m from the east-northeast, period at 8 seconds, and the energy hits moderate (556). Light cross-offshore wind keeps it clean. This is the first session worth paddling for, but it’s short-lived as the wind goes onshore in the afternoon.

The weekend is a wash. Saturday is blown out with strong onshore wind. Sunday morning the 23rd is messy but surfable, with 1.5m from the south-southwest and light cross-off wind.

Now for the standout. Monday afternoon the 24th. Swell is 1.8m from the south-southwest, with an 11-second period, and the energy is strong (1256). It’s glassy – dead calm. This is excellent surf for experienced surfers, with clean, powerful lines. The direction is a bit off the optimum, but the quality is hard to beat. Crowds are *sometimes* an issue here, so expect a few others out.

Tuesday the 25th gets big. Swell hits 3.0m from the south, with a 14-second period, and the energy is massive (3091). This is expert only. The wind is cross-off, but the size will be too much for most. It drops to 2.5m in the afternoon, but still heavy.

The quality holds through Wednesday the 26th and Thursday the 27th. Swell drops to 2.0m and 1.8m from the south, with long 13-14 second periods and excellent energy. Mornings are clean with offshore winds. These are your best days after Monday.

Then it fades. The last week of August into September is small again, with weak energy and mostly messy wind. There’s a pulse on the 2nd of September with 1.8m from the south-southeast, but it’s marginal.

The best bet is Monday the 24th through Thursday the 27th. Clean, long-period groundswell. Get after it.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
